No, but 2,2,3,4 would count as 2 runs of 3 and would score 6 plus 2 for a pair, ie a total of 8. If the turn card were say another 4, that would be 12 for runs, 2 for a fifteen, plus 4 for pairs, ie 18.
But 2,3,4,5,6 only counts as 5 for a run plus 4 for 15s, ie 9.
I would suggest you take up bridge - harder but more fun.
